No. One Maya eSIM on the Global + Cruise plan, priced on its own, connects you on 20+ cruise lines and in 165+ countries, installed once and kept on your phone. Carnival sells its onboard Wi-Fi plan by plan, by the day.

A day rate for the ship’s Wi-Fi, then a phone with no signal the second you walk down the gangway. Every port day starts with the same hunt for a connection.

Does a Maya eSIM work on a cruise ship at sea?

Yes, with the Global + Cruise plan, which is its own purchase and covers 20+ cruise lines with unlimited data at sea. That includes Carnival Cruise Line and Norwegian Cruise Line.

Out on open water, no land tower reaches you. Cellular at Sea (2026) says ships in its network carry their own onboard cellular network, and the signal switches on when you are in international waters, about one hour from port. Its own words on the bill: “Your usage at sea is billed by your home cellular carrier under its roaming terms, so ask what your plan includes for cruises before you sail.”

That is a question you ask your carrier before every sailing. With Maya, you buy a plan for the trip length you pick, and the price is set before you board.

Maya Mobile is a travel eSIM giving you unlimited data in 165+ countries and 20+ cruise lines through a single eSIM permanently installed on your phone. You don’t carry a stack of SIMs or line up at a kiosk. You install once and the same eSIM rides along on the next sailing.

What do you use for data in port after you leave the ship?

Carnival sells Wi-Fi for keeping you connected at sea, so the port day is a separate problem. The same Maya eSIM works in 165+ countries with automatic network switching and no physical SIM swaps.

Carnival’s own plans page puts it this way: “To keep you connected while at sea, all ships provide satellite internet access at our internet cafés and through the bow-to-stern ship-wide Wi-Fi network.” That is the ship’s service, and it is sold by the day.

Your home carrier has a day rate for land too. AT&T’s website says: “Use your wireless plan in 210+ destinations with unlimited* talk, text, and high-speed data for $12/day.” That is a charge for each day the phone is used abroad. A Maya plan is one price for the whole trip length, so a port stop doesn’t start a new meter.

One Maya plan covers the Caribbean, Puerto Rico and Spain, plus 165+ destinations worldwide. Jb gave Maya five stars on Trustpilot on February 11, 2026: “I’ve used their eSIM solution for internet data for two phones in Egypt (Hurghada), Mexico (Cancun) and now I bought it for vacation in UAE – Thailand. I’ve bought one data plan with wrong date, but their support was super friendly and changed the dates to correct ones. Great support and great coverage in all countries so far!!!”

What should you check before buying an eSIM for a cruise?

Check that the plan names cruise ships, because ship coverage is the Global + Cruise plan, bought on its own. Then match the price to your trip length.

We publish these Global + Cruise prices in our terms:

  • 3 days: USD 49.99
  • 7 days: USD 109.99
  • 30 days: USD 299.99

Cruise coverage never rides on a Global plan price. Add-ons are purchased separately and carry their own availability and conditions.

Next, read how “unlimited” is defined. Our terms give a daily high-speed allowance at up to 4G LTE or 5G where local networks offer it, reset every 24 hours. Unused daily quota doesn’t carry over. Maya’s Unlimited eSIM plans, including add-ons such as Global Cruise Connectivity, are designed for individual travelers using data on the move.

Rivals publish allowances too, so find the allowance line in each company’s terms before you pay.

Last, coverage. Cruise connectivity runs on satellite and maritime networks and depends on vessel and route availability, so check your ship and itinerary against the cruise line list.

What each travel eSIM publishes on cruise coverage and daily data

We sell one global eSIM for 165+ countries at a flat price by trip length, with the Global + Cruise plan priced on its own for 20+ cruise lines, while Airalo, Holafly, Saily and GigSky each publish their own plan structure and daily terms. Read the cruise and allowance columns against your sailing.

Travel eSIM How plans are sold Unlimited plan allowance, as published Cruise plans, as published
Maya Mobile One Global eSIM for 165+ countries, unlimited data at a flat price by trip length: USD 9.99 for 3 days, USD 19.99 for 7 days, USD 27.99 for 14 days, USD 49.99 for 30 days A daily high-speed data allowance (the Daily Quota) at up to 4G LTE or 5G where local networks offer it, reset every 24 hours; unlimited data at standard speed once the Daily Quota is used Global + Cruise plan for 20+ cruise lines, priced on its own: USD 49.99 for 3 days, USD 109.99 for 7 days, USD 299.99 for 30 days
Airalo Per country, per region, or one global plan; priced in USD Our unlimited data packages don’t have a fixed total data cap. However, to keep the network running fairly for everyone, when you use more than 3GB in a day, we’ll slow down (or “throttle”) your internet speed to 1 Mbps for the rest of that day. No cruise plan published
Holafly Per country, per region (Europe, Latin America, Cruise plans), and unlimited monthly/annual global plans Unlimited data means there is no fixed limit on the amount of data you can use. However, some network operators may temporarily reduce your speed after a certain amount of high-speed data usage, as explained above. If you buy an eSIM for travel on a Caribbean cruise, you’ll only have coverage on land, and a connection is not guaranteed while sailing. In the Bahamas, please note that service is unavailable in Freeport, CocoCay, and Ocean Cay, although it remains available at the other ports.
Saily Per country and per region, plus one global plan; by the gigabyte, unlimited, or both The Unlimited plan gives you 5 GB per day at full 4G/5G speed, then keeps you online at 1 Mbps for the rest of the day — fast enough for navigation, messaging, and standard browsing. No cruise plan published
GigSky Per country, per region, and cruise plans; by day, unlimited data with 3.5GB daily high-speed allowance Get up to 3.5GB/day at our fastest speeds: Video calls, uploads, streaming and more. You can use GigSky on 200+ cruise ships (Royal Caribbean, Carnival, Norwegian, etc.) and in 200+ countries on land.

Each rival’s cells are its own published words, or a short summary of what it states, read from its own site on October 9, 2026; the Maya Mobile cells are from maya.net.

How Maya Mobile puts a whole cruise week on one flat-price eSIM

A ship’s day rate and a hunt for a signal in port are two problems, and we sell one fix. Install the Maya eSIM once and it stays on your phone, so the same eSIM goes from sea day to port day in 165+ countries.

On land, the Global plan runs 3, 7, 14 or 30 days at one flat price, from USD 9.99. For ship coverage on 20+ cruise lines, the plan is Global + Cruise, priced on its own for 3, 7 or 30 days. Need more days mid-trip? Buy another plan from the Maya app. On iPhone, name the plan “Maya eSIM” or after the country you’re visiting, so you can find it fast.

Enrico M. gave Maya five stars on Trustpilot on March 31, 2026: “Incredible value for money and super efficient customer service. The global list of countries they cover is truly global, differently from many other esim suppliers, and we are so grateful to Maria V. for successfully and quickly resolving a small issue. We could not recommend more!!”

Frequently Asked Questions

What happens after the daily high-speed allowance on a Maya eSIM?

Data keeps running at standard speed for the rest of the day, and the allowance resets automatically every 24 hours. Every plan includes a daily high-speed allowance at up to 4G LTE or 5G where local networks offer it. Unused daily quota doesn’t carry over, and we don’t guarantee specific speeds; actual speeds vary by location and local network conditions.

Does a Maya eSIM renew on its own?

No. Maya plans are one-time purchases, and nothing is charged after a plan ends unless Auto Top-Up is on. Auto Top-Up is optional and off by default. With it on, the same plan is bought again automatically when the current one expires.

Can I reuse my Maya eSIM on my next cruise?

Yes. The eSIM stays installed on your phone, and each trip needs a plan. For a cruise, that plan is Global + Cruise, bought as its own purchase. Most eSIM-compatible devices support multiple eSIM data plans installed at the same time.

Does Carnival offer free Wi-Fi onboard?

No. Carnival’s internet plans page lists Social, Value and Premium as paid plans, and the Social plan’s pre-cruise rate starts at $20.40 USD per day. Carnival’s help center says the HUB app is free to download and use on board. It works in Airplane Mode, so guests don’t incur roaming fees, and chat costs a small additional fee.

Can you save money by buying Carnival Wi-Fi before you sail?

Yes, Carnival says you save up to 15% when booked prior to sailing versus onboard pricing. The Social plan starts at $20.40 per person per day pre-cruise and costs $22.00 onboard, and it covers the most popular social websites and apps while excluding most other websites, email, video and music streaming. The Premium plan starts at $25.50 per person per day pre-cruise and costs $28.00 onboard. The pre-purchase cutoff is 11:59PM EST the day before embarkation, and additional restrictions apply.

How do you avoid a roaming bill from a ship’s cellular network?

Cruise Critic (2026) says Cellular at Sea is not usually included in your roaming package, costs extra, and can bring charges higher than expected. Your home carrier typically won’t add roaming fees for data while the Maya eSIM carries it, as long as the eSIM is installed correctly and Data Roaming is off on your home line. Keep your phone set to use the Maya eSIM for data. Service in a specific country isn’t guaranteed and can vary for reasons outside our control, and no speed is guaranteed.
